Does this sound off? If so, how to make it work?

We've decided on Helena [hel-EHN-uh] if it's a girl. Yay! Middle name will be Cora but we wanted to add another. Astrid. I don't know why, but we adore it. Does HelenaCoraAstrid sound off? If so, what arrangement could sound better? Cora could possibly change to Corinne, Cori, Coraline, etc. but Helena won't change. Thanks so much!

It does sound kind of strange, mainly because of the double -a endings immediately followed by an A name. I think Coralie fix both those problems, and though the flow isn't quite perfect, it is certainly improved. HelenaCoralieAstrid? What do you think?
